Antenna design for compact RFID sensors dedicated to metallic environments

Abstract

In this paper, the design and simulation of a Radio Frequency Identification (RFID) antenna is presented. The antenna is designed in order to maintain a small size while operating on metallic surfaces. This RFID antenna with an appropriate chip is intended to be used as RFID sensor. The RFID tags designed for metallic environment have to overcome certain drawbacks regarding the effects of metal to the performance of the antenna. These effects are being addressed in this work and certain solutions are explored. Finally the results of the simulation of the antenna are presented to evaluate the performance of the antenna.
